Do you tell by horsepower or torque. and how does weigth play into this. because a lighter car with less horsepower can go faster than a heaver car with the same horsepower. But how do you tell how much horsepower you will need to have the same speed/acceleration as the lighter car. Do you divide the horsepower into the weight?

Correct. Its called the "power to weight ratio". Roughly, it means that a 1000 lb cat with 200 hp should be roughly equal in acceleration to a 2000 lb car with 400 hp.
Of course, this does not take into account inertia, the characteristics of the motor, the size and position of the usable power band, the available gearing, momentum under brakes, momentum under cornering, tyre width (wider tyres = higher rolling resistance), aerodynamics, and a whole bunch of other things. Power to weight ratios are only the start.

Dinos can test the horse power of any engine.

You didn't take gearing intp account.
